Hello
I'm trying deploy rpclib application via apache mod_wsgi.
Tested service by suds app, but didn't get response from service.
handler.wsgi: http://pastebin.com/Yf3eve8d
Service debug output: http://pastebin.com/angUhsyC
Before this in development I used wsgi server from standart python lib
and got output from service on start: http://pastebin.com/8Z1NfPDE
btw, I used the same suds client but with different wsdl strings.

Hi,

don't know what exactly you are doing wrong but my WSGI file looks very different (and is working fine):

Hello,

I think there is a bug in the rpclib.model.primitive.Date class :
from_string result should be

datetime.date(int(fields['year']),  int(fields['month']),  int(fields['day']))

(missing int() for all params)

Subject: [Soap-Python] rpclib and Content-Length header?
Message-ID: <9A28849130E63E458AF1BA7CB17E2F3E6CD3CCDA@exchange2.mypublisher.local>

Hello,

I've written a SOAP service using rpclib 2.6.1-beta1 (originally with 2.5.2, same issue) and I'm noticing that the Content-Length header is never being set on the response from the application.

This is causing undesirable behavior when the application is mounted with uWSGI in Apache (sometimes Apache is adding the Transfer-Encoding: chunked header), so I'm attempting to figure out how I can correct this so that the Content-Length is always being set.  I noticed that protocol/soap/mime.py has code to deal with Content-Length, so to activate this I tried setting _mtom=True in my method decorator, but this led to a traceback first stating that out_object was being used before declaration in line 301 of server/wsgi.py.  I adjusted it thusly:

                out_object = ctx.out_object
                if len(out_type_info) == 1:
                    out_object = [out_object]

But then I get another traceback from the next line complaining that out_object is not iterable:

Traceback (most recent call last):
  File "/usr/local/pkg/python-2.7.2/lib/python2.7/site-packages/rpclib-2.6.1_mypub-py2.7.egg/rpclib/server/wsgi.py", line 200, in __call__
    return self._verb_handlers[verb](req_env, start_response)
  File "/usr/local/pkg/python-2.7.2/lib/python2.7/site-packages/rpclib-2.6.1_mypub-py2.7.egg/rpclib/server/wsgi.py", line 310, in handle_rpc
    out_object
  File "/usr/local/pkg/python-2.7.2/lib/python2.7/site-packages/rpclib-2.6.1_mypub-py2.7.egg/rpclib/protocol/soap/mime.py", line 249, in apply_mtom
    name, typ = params[i]
TypeError: 'ComplexModelMeta' object is not iterable

So... basically I'm guessing that I'm in uncharted territory here and this code must not get used often.  I'm not sure that the MtoM path is what I really need, I'm ultimately just trying to figure out how to get the Content-Length header set in the response message from the service.

Any thoughts on this?

Thanks!

Hi Kevin,

To set the Content-Length header, you have to have the whole response 
in memory. And since the beginning my aim has been to have rpclib work 
without having the whole message in memory in order to have the ability 
to return HUGE responses. (see the roadmap document) So I've 
intentionally suppressed the Content-Length header from responses. But I 
never thought this would have side effects. So here's a quick patch for 
that: 
https://github.com/plq/rpclib/commit/7092617b74bd6b3a2d57fd9833336b851208a672

Does it work for you?

You're right, There's been a long time since I touched the mtom code. I 
doubt it works at all.

Subject: [Soap-Python] gist: 1242760 Unable to run with Django
Message-ID: <1331135284.7271.8.camel@banana>

Hi,

based on the information in the comments section of the Gist, I am
unable to run rpclib in conjunction with Django 1.4c1 and Apache
mod_wsgi.

The Apache server simply blocks upon the first request. When doing an
strace on the processes I can see that some xsd file are generated
in /tmp and after that nothing happens. No pages are served by this
Apache anymore.

Could you help me to track down the problem, I used in my tests the
following code:

from rpclib.server.django import DjangoApplication # not real import
path.
from rpclib.model.primitive import String, Integer
from rpclib.model.complex import Iterable
from rpclib.service import ServiceBase
from rpclib.interface.wsdl import Wsdl11
from rpclib.protocol.soap import Soap11
from rpclib.application import Application
from rpclib.decorator import rpc

class HelloWorldService(ServiceBase):
    @rpc(String, Integer, _returns=Iterable(String))
    def say_hello(ctx, name, times):
        for i in xrange(times):
            yield 'Hello, %s' % name

hello_world_service = DjangoApplication(Application([HelloWorldService],
        'some.tns',
        interface=Wsdl11(),
        in_protocol=Soap11(),
        out_protocol=Soap11()
    ))

and replaced based on the comments:

from rpclib.server.django import DjangoApplication # not real import
path.
by:
from rpclib.server.wsgi import WsgiApplication

and modified the service definition into:

hello_world_service=WsgiApplication(Application([HelloWorldService],
        'some.tns',
        interface=Wsdl11(),
        in_protocol=Soap11(),
        out_protocol=Soap11()
    ))

Both examples are blocking my server.

Thanks for your help.
Raoul

most probably, this is your problem:

http://mail.python.org/pipermail/soap/2012-January/000704.html

i'd just use a reverse proxy setup instead of mod_wsgi.

The solution is adding

WSGIApplicationGroup %{GLOBAL}

in apache conf. Thanks again to Burak :)

Hi,

thanks for the update, as my message didn't appear on the list I could
not send an update.
After turning debugging on and learning some new techniques to work with
mod_wsgi it turned out that WSGIApplicationGroup %{GLOBAL} must be
enabled in conjunction with lxml and therefore also for rpclib.

That's not quite true.

Using WSGIApplicationGroup %{GLOBAL} is one possible solution, but it
can also cause problems.

Another possible solution is to use WSGIDaemonProcess as mentioned in
the article that Burak linked to.

This is not true. You have to use %{GLOBAL} also when using WSGIDaemonProcess. If you are running several applications using lxml, create several WSGI processes (one per app).

OK, it seems you would need WSGIApplicationGroup (but it's not clear
to me that it MUST be %{GLOBAL}).

It seems that %{GLOBAL} is the way to go with WSGIDaemonProcess too:

http://stackoverflow.com/questions/5021424/mod-wsgi-daemon-mode-wsgiapplicationgroup-and-python-interpreter-separation

So the safest option seems to use both, but you might be able to get
away with only WSGIApplicationGroup %{GLOBAL} depending on the
circumstances.

Hah, this is because that user don't understand how mod_wsgi works. Of course that this happened cos he used the same WSGI process and the same application group for all sites. It's his fault and it's not caused by %{GLOBAL} usage. You should:
1.) use different application group for _every_ site/application
2.) if (1) is not possible (for example, all sites needs to use lxml so all of them needs to run in %{GLOBAL}), use different wsgi process for _every_ such site/application

Of course, but my point is it's not enough to tell someone "Just use
WSGIApplicationGroup %{GLOBAL}" :)  They might also need to use daemon
processes.

Well i don't see much reasons why NOT use daemon processes. It's much more flexible and faster and it's like some kind of python application server which is cool. If you are running inside apache processes, everything must be reinitialized with every reuqest.

Subject: [Soap-Python] Implement a server from an existing WSDL specification
Message-ID: <1284295936.20120316202029@gmail.com>

Hi everyone,


I am glad I discovered this list, I've read most of the conversations
from the "beginning of time" up to this day and I am looking forward
to interacting with you. 

SOAP is a new concept for me, there are questions I hope you can help
with. I am not intimately familiar with the terminology, so I suspect
some of the questions may be dumb.


The service I am working on must comply with an existing WSDL
specification: http://pastebin.com/vqVpGix1 (standardized in ETSI
102.204)


My questions are:
1. what is the recommended approach for writing a SOAP server that
   implements an existing WSDL?

2. which of the existing frameworks
   a. supports basic types such as xsd:anyURI, xsd:dateTime or
      xsd:base64Binary?
   b. allows the declaration of enumerations and their possible
      values?
   c. allows the declaration of custom types for which some
      information is passed not as an XML element, but as an
      attribute?
   d. allows the use of custom complex types that are defined in an
      existing namespace?  (I think this is the same as [a], but am
      not entirely sure about it)

3. are there any books on SOAP/XML and Python you can recommend? If
   there is no Python-specific literature, perhaps there are good
   books about SOAP/XML in general?








The part below is optional :-), it describes my experiences with
SOAP/XML in Python. 



Having studied the available tools, I chose to go with Ladon, because:
- the description makes it look very simple
- the syntax is straightforward and concise
- it has very clear examples
- documentation is generated automatically

I was able to create a simple SOAP/XML server and call its functions
within an hour, it worked just as advertised.


Surprisingly, I only found 2 references to Ladon on this mailing list,
it seems that the rest of the world is doing something completely
different.


Although my first experience was very positive, later I realized
things may be more complicated than I anticipated.

Ladon makes it easy to write services from scratch, I focus on the
logic, and the WSDL is automagically generated.



However, my actual objective is to take an existing WSDL and implement
its rules in my own code. Since my WSDL is relatively simple, it has 7
functions (not sure if this is the proper SOAP terminology) - I
figured I'd just define my classes and functions accordingly, such
that the generated WSDL is identical to the reference WSDL.

This is where things got tricky. While everything is easy with
primitive types such as strings or numbers, the XML schema of the spec
has a lot of other types in it, simple ones such as anyURI or NCName,
and complex ones.

These two examples I gave are still strings, but they have some
constraints applied to them. If I declare them as strings, I can
perform all the necessary checks myself, but the generated WSDL file
doesn't look right (because "xs:string" and "xs:anyURI" are
different). This is probably going to cause compatibility issues with
systems that are supposed to use my service when it is released.


My conclusion was that I would have to define them as custom types
derived from primitive types, but.... this simply doesn't feel right,
because it involves reinventing a lot of things.




Then I turned to ZSI, as people say it generates code from the given
WSDL - it sounded that this was the thing I needed. I was also hoping
it would take care of defining all the types for me.

ZSI seems pretty arcane and not very alive (even though the mailing
list seems to be somewhat active) - I am not sure if it is a good
choice.


I hope you weren't bored to death by the account of my SOAP
adventures.


Alex





p.s. if anyone ever visits Moldova, I'd be happy to show you around
:-)

Hey there,

So I guess you're the first person I've come to meet online or offline 
who actually enjoys working with soap :)

Your message is huge, yet entertaining, so I've actually read it all. 
Top posting answers to prevent this thread from explosing in length:

1) You do it manually, from scratch. This comes up a lot, and I believe 
someone just will do it sometime.

2) Rpclib supports all this, and it also supports other protocols. It 
doesn't support NCName, but to get that you just need to:

from rpclib.model.primitive import Unicode

class NCName(Unicode):
     __type_name__='NCName'

and you're set. send me a pull request if that works for you.

3) Nope. Java ecosystem has plenty of those though.

Avoid ZSI, SOAPPy, SOAPpy, they're not maintained anymore. Use 
maintained packages like Rpclib, Ladon or PySimpleSoap for server and 
SUDS for client.

Best Regards,
Burak

PS: I'm totally going to steal ladon's documentation generator :)

Hi Burak, thanks for the swift response. I've played with rpclib over
the weekend.


I noticed that the documentation is lacking several chapters (ex:
input validation). I'd like to contribute to that part, as I think it
will be the most effective way to familiarize myself with the
software.

Basically, I want to extend the docs by writing examples for custom
types that have:
- their own validation rules
- additional attributes besides the typical ones like minOccurs or nullable
- a limited set of possible values (enumerations)


Other questions may come to the surface in the meantime, but these are
the ones I asked in the beginning of my journey and these are the ones
I want to provide answers for. If things go as planned, I could also
write more about implementing a WSDL by hand. These are obvious to
someone who has been doing this for a while, but for someone with no
prior exposure to WSDL or SOAP (such as myself) - it's not trivial.



> So I guess you're the first person I've come to meet online or offline who actually enjoys working with soap :)
Oh, it's not because I like SOAP, it is because I love Python - it
makes everything look one-two-threasy :-)




Let me begin with validation rules. Is it appropriate to discuss
everything here, or should I just fork, write what I think is a
reasonable intro to this matter?

well, i'm happy to answer any questions you might have. validation needs 
both more tests and docs, so there's definitely a lot to do there.

you can start with small contributions. i'll review these for you 
quickly. later as we go along, you can increase your pace.

Message-ID: <CANK1NR2-6BJB7TyarAPZC_2TyxGbN4gR2xZ4U1j8bKnckOY13A@mail.gmail.com>

Burak,

In parallel with writing the documentation for input validation in
rpclib, I am trying to apply rpclib to solve the problem that brought
me to this list in the first place.

I began creating my custom types and I ran into some cases which don't
seem to be straightforward.



One of the types looks like this

<xs:complexType name="DigestAlgAndValueType">
	<xs:sequence>
	<xs:element name="DigestMethod" type="ds:DigestMethodType" minOccurs="0"/>
	<xs:element name="DigestValue" type="ds:DigestValueType"/>
	</xs:sequence>
</xs:complexType>


ds:DigestMethodType is in another namespace, the link to which is
given in the beginning of the WSDL file. If I understand things
correctly, I have to create a custom class for DigestMethodType and
override its __namespace__ = 'ds'. Can you confirm that?

(1) It is also necessary to modify the top of the generated WSDL file
and include a link to the document that defines the 'ds' namespace.
How to do that? I supposed I could also override the namespace with a
URL to the XML file itself, but is that a good practice?



DigestMethodType itself is a tricky beast, this is the definition:
http://xml.fmi.fi/namespace/woml/swo/2011/11/15/index790.html

<complexType name="DigestMethodType" mixed="true">
  <sequence>
    <any namespace="##other" processContents="lax" minOccurs="0"
maxOccurs="unbounded"/>
  </sequence>
  <attribute name="Algorithm" type="anyURI" use="required"/>
</complexType>

(2) how does rpclib handle 'namespace="##other"'? My understanding is
that it means I can add an arbitrary number of elements of any type.
The closest match I could find is AnyXml or AnyDict (declared in
primitive.py). However, I am not sure how to use it; test_primitive.py
doesn't cover these two classes.

(3) 'use="required"' - the 'use' attribute is not declared in the
AnyUri class, neither in Unicode or SimpleModels (the classes from
which it was derived). It seems to be a basic attribute; was I unable
to find it? Or is it really not there?

(4) 'mixed' is another attribute that I didn't find declared in the
base class of the ComplexType class? Does one really need it? I mean,
maybe it is assumed that all the ComplexType children are mixed by
default?



There's another data type with the poetic name 'DataType' :-)

<xs:complexType name="DataType">
	<xs:simpleContent>
		<xs:extension base="xs:string">
			<xs:attribute name="MimeType" type="xs:string" use="optional"/>
			<xs:attribute name="Encoding" type="xs:string" use="optional"/>
		</xs:extension>
	</xs:simpleContent>
</xs:complexType>


I've seen how to declare elements and attributes in a custom type, but
this is something new to me. It feels like some kind of inheritance,
so:

(5) How to declare such a type?


I will update the documentation and add some examples of this as soon
as I figure it out myself.

Alex

no, ds is just the prefix. you need to find the xmlns:ds attribute and 
use its value as the value of the __namespace__ attribute. Here's how 
the above would look like:

class DigestValueType(ComplexModel):
     __namespace__ = "some_ns"

class DigestMethodTypeComplexModel):
     __namespace__ = "some_ns"

class DigestAlgAndValueType(ComplexModel):
     DigestMethod = DigestMethodType
     DigestValue = DigestValueType.customize(min_occurs=1)

Ah. Rpclib does not support that directly. But I've just committed 
support for the 'document_built' event in the InterfaceBase. so if you 
register an event for that and make the desired changes to the generated 
wsdl document directly, you can do that.

Rpclib can't generate this schema, you'd have to come up with a patch to 
the xml schema implementation that actually emits an <any/> tag.

No, it isn't there. I actually didn't know about this. Why not just use 
min_occurs=1 ?

That isn't supported either. XML Schema specification should say the 
default value in case of abscence.

You can't. Rpclib only supports simpleType extension via restrictions, 
not attributes.

I guess this wasn't much of help but what can I say, patches are welcome...

I think "use" is for attributes, whereas "min_occurs" is for elements.
http://www.w3.org/TR/xmlschema-0/#OccurrenceConstraints


I've done some digging in complex.py and I saw that the XmlAttribute
class has a describe() function that does look for a "use" argument.
Is this not the solution?


> class DigestAlgAndValueType(ComplexModel):
>      DigestMethod = DigestMethodType

The call to customize() returns an object of DigestValueType and
overrides the min_occurs property with 1, right?

Why not just declare DigestValueType with min_occurs=1 from the very
beginning?

Ok, I will try to simplify the problem then.  Since those who will use
my server already have the WSDL, it is not critical for me to be able
to produce a WSDL that looks exactly like the one given in the
specifications. 

However, it is critical for me to be able to receive such a request
and be able to handle it.

If I create a custom type like this, will it do the trick?

class DataType(ComplexModel):
    class Attributes(ComplexModel.Attributes):
        MimeType = XmlAttribute(String, use = 'optional')
        Encoding = XmlAttribute(String, use = 'optional')

I've examined the source and this seems to be the place to tinker
with:  src\rpclib\interface\xml_schema\model\complex.py

But besides generating such a schema, there must also be a way to
represent such a structure in the custom type definition, which
happens here: rpclib\src\rpclib\model\complex.py

Can you confirm that this is the case?

In addition to that, it would be great if you could offer some
tips about implementing this. I am not yet familiar enough with the
guts of rpclib to be able to make such fundamental changes.

that's possible.

class DigestValueType(ComplexModel):
     __namespace__ = "some_ns"
     class Attributes(ComplexModel.Attributes):
         min_occurs=1

Nope. the class Attributes has nothing to do with xml attributes. It 
used to be, but I could not think of a way to handle elements attributes 
with same name. So I decided to avoid the problem and decided to have 
attributes and elements put in one namespace. It's still named 
Attributes because of backwards compatibility. It's currently just a way 
to store metadata.

Anyway, you should do this:

class DataType(ComplexModel):
     MimeType = XmlAttribute(String, use = 'optional')
     Encoding = XmlAttribute(String, use = 'optional')

Here's what that generates:

<xs:complexType name="DataType">
<xs:sequence/>
<xs:attribute name="MimeType" type="xs:string" use="optional"/>
<xs:attribute name="Encoding" type="xs:string" use="optional"/>
</xs:complexType>
<xs:element name="DataType" type="s0:DataType"/>

Which is not what you want. However, If you use no validation or soft 
validation, you can receive fields like this:

<field_name type="xs:string" Encoding="this" 
MimeType="that>some_string</field_name>

lxml validation will just reject this, because the additional attributes 
are not in the schema. but soft validation should work because it 
ignores unknown fields.

Once you get the message, you'll have to dig the values out of 
ctx.in_body_doc using xpath or a similar method. xpath is a very simple 
way of processing xml data, and lxml offers great support for that, so i 
don't imagine it'll be an issue.

Yes, these are correct.

That will partly depend on the kind of API you want to offer. You'll 
most probably implement a class similar to XmlAttribute. The metaclass 
in ComplexModel scans cls_dict to extract rpclib-relevant attributes and 
puts them in the _type_info attribute. The Xml schema implementation in 
the rpclib.interface package uses this information to generate the 
schema document.

And I imagine the funky thing that'll make the code hard to follow there 
is cdict. It's a special kind of dict that accepts classes as keys and 
any data as value. It tries parent classes as keys if it can't find the 
given class itself. See this for more info: 
https://github.com/plq/rpclib/blob/f7dc3b87feaa97953eeb12a92c367f23314ac243/src/rpclib/util/cdict.py

Other than that, I think it's a fairly straightforward implementation. 
Regardless, I'm happy to answer your questions.

Best,
Burak

Hi,

I am going to try to create a basic service, after that I'll be able
to understand better how the sources work. Until then I have
insufficient competence to decide which of the solutions you suggested
is better.

My hunch is that it is better to alter the XML schema generation
mechanism such that it generates the schema I want, instead of turning
off validation or using soft validation (because I will lose all the
checks that lxml would otherwise do for me) and parsing the string
myself at a higher level.

I've used XPath and I even made some screencasts about it:
http://www.youtube.com/watch?v=7RiW2g-AKbs
http://www.youtube.com/watch?v=PgWfF-Ut0zM


I think it would be great if we could make such screencasts about
rpclib, that would definitely make it more accessible to inexperienced
folks such as myself.

My current priority is to focus on the creation of these custom
classes, but I will happily accept to work on the video tutorials or
write more documentation, if someone else can help me by creating
those classes (assuming that they're relatively easy to implement for
someone familiar with the intimate details of rpclib).

The operation I am trying to call is:

     <xs:element name="args0" type="mcxs:LoginInfo"/>

    <xs:element name="user" type="xs:string"/>
    <xs:element name="password" type="xs:string"/>

However, when I attempt to call it with:

     client = SoapClient(wsdl='http://myserver:9443/services/mcService?wsdl', trace=True, soap_server='axis')
     client.login({'user': 'test', 'password': 'xxx', 'client': 'tester', 'domain': '/', 'locale': 'en_US'})

The server does not like the request:

Am I doing something wrong here? I have a feeling it has to do with namespaces not being prefixed to the individual parameters. Any help is greatly appreciated!

I agree, the cllient you're using (I don't recognize the api) is sending 
an invalid request. Did you try it  with suds? Try this:

from suds.client import Client
client = Client('http://myserver:9443/services/mcService?wsdl')
client.service.login('test', 'xxx', 'tester', '/', 'en_US')

You might have a look at "dm.zope.rpc.wsdl_suds".

It does something like this for Zope 2, using suds for SOAP
demarshaling/marshaling.

The Zope 3 way would be to register a SOAP view (rather then a browser
view) and do their demarshaling, call the function and marshal the result.

Subject: [Soap-Python] Customizing rpclib with types that modify the schema
Message-ID: <359299370.20120329193224@gmail.com>

Hi everyone,


I wish to extend rpclib with the possibility of generating a schema
with an "any" tag:

<any namespace="##other" processContents="lax" maxOccurs="unbounded"/>


I also want to document the process, so others will have a clue about
it.



What I think I have to do:
1. add a new class to the list of primitives
2. change the code that produces XML from a Python class
3. change the code that generates a Python object from XML
4. extend the tests, such that they include the newly created type



My questions are:
a. are there any other steps that I missed?
b. which class should I inherit from?
   - AnyXml and AnyDict seem reasonable candidates, their names are
     very attractive. However, I did not find any examples of how
     they are used
   - if my guess is correct, then this will be a simple matter of
     creating a derived class and setting __namespace__ to '##other'.
     This sounds too good to be true.
c. what are the functions that have to be overridden in the new class?
d. how to tell the parser about "processContents", "namespace" and the
   behaviour specified by its different values?
   - I think it can rely on validate_native, but my understanding is
     that I must also define the behaviour of validate_native for this
     type - I don't know where to do that
e. is there any documentation about this? Some kind of howto?
f. which other questions was I supposed to ask? :-)



Looking forward to your feedback.

Hi,

I thought if I'd just start implementing this, it'd help you more than a 
300-word reply.

I skimmed the spec very quick and from what I gather, you want an <any> 
tag instead of an <element> tag inside the <complexType><sequence> (...) 
</complexType></sequence> hierarchy, right? (correct me if i'm wrong here.)

if so, here's the patch that is a nice starting point:

The first hunk makes the element tag name parametric.

The second hunk adds the parameter to the ModelBase class.

So if you want an <any> tag instead of an <element> tag inside a 
complexType definition, you need to do this:

class SomeType(ComplexModel):
     child = AnyXml(schema_tag='{%s}any' % rpclib.const.xml_ns.xsd, 
namespace='##other')

This is totally off the top of my head, but I guess you get the idea.

Does this help? Let me know how it goes.

best,
burak

there's no such thing in rpclib. we don't parse xml schema, only 
generate it.

You need to re-implement any additional validation that the the schema 
validation does in the soft validator as well. In this case, I agree 
that validate_native in AnyXml is the right place to do it.

https://github.com/plq/rpclib/commit/811f29e0ec83ffb38a479511cbc91db6430b799d

fork this and submit a pull request to the arskom/rpclib when you're 
finished if you think it is a nice start.
